Charging the Internal Battery using the Built-In Charger:

7.2 

To charge, plug an 18 gauge (AWg) or larger extension cord into the 

1. 

charger plug on the side of the jump starter. (Extension cord not included; 

must be purchased separately.)
Plug the extension cord into a 120v AC electrical wall outlet. 

2. 

The CHARgINg (red) LEd will glow indicating charging.

3. 

The FULL (green) LEd will light when the battery has reached full charge. 

4. 

This could take up to 72 hours due to the age and condition of the battery. 

The charger will automatically go into maintain mode and maintain the 

battery at full charge without damaging it.
Charge the jump starter as soon as possible after use.

5. 

 do not use the jump starter while charging the  

internal battery.
You may also charge the internal battery while driving, using the male-to-male 

charger cable (p/n 94500109 – not included). Insert one end of the accessory 

cable into the 12v dC power outlet and the other end into the vehicle’s 

accessory outlet (lighter socket). Completely disconnect the charger cable 

when the engine is not running. 

The CHARgINg (red) LEd and the FULL (green) LEd do not 

operate during this method of charging. Using this method to charge the 

battery overrides the maintain mode and the battery can be overcharged. 

Monitor the progress of the battery and when it reaches a full (100%) charge, 

disconnect the charger. do not leave the battery unattended or it could explode 

causing property damage or personal injury.
